Is it possible to give your cats their shots yourself? I would of course still bring my cats in for their check ups, but with the number of cats I have it would probably save me $$ to give my own shots like I do w/ my goats. All my cats are rescued and spayed/neutered. How do you learn what shots to give and how to give them, and where is the best place to buy them? My town gives only rabies for free. Thanks alot...
